Summary

The contract test service now declares four capabilities that the SDK already supports, so the harness tests they gate now run:

• context-type: the contextBuild and contextConvert handlers already existed. This turns on the context type/build and context type/convert tests.
• context-comparison: adds the contextComparison command, which builds both contexts and compares them with LDContext.equals.
• wrapper: maps wrapper to HttpConfigurationBuilder.wrapper. The harness sends an empty string for an unset name or version, so the service treats it as unset.
• fdv1-fallback (v3): reads dataSystem.fdv1Fallback. Its base URI becomes the polling endpoint, which the SDK's FDv1 fallback synchronizer uses. This turns on the streaming/fdv2/FDv1 fallback directive tests.

It also removes streaming/fdv2/fallback to FDv1 handling from testharness-suppressions-fdv2.txt. No test at v3.2.0-alpha.10 has that name.

Tested with this PR's CI. The emulator does not boot locally on this aarch64 host, which has no KVM, so I only built the APK locally.

Note

Overview
The Android contract test service advertises four new harness capabilities (context-type, context-comparison, wrapper, fdv1-fallback) so gated conformance tests can run against behavior the SDK already implements.

Config wiring: harness wrapper name/version map to HttpConfigurationBuilder.wrapper, with empty strings treated as unset so headers are not sent blank. When a data system config is used, dataSystem.fdv1Fallback.baseUri sets the top-level polling endpoint used by the SDK’s FDv1 fallback synchronizer.

New command: contextComparison builds two contexts (single or multi-kind, attributes, literal/path private attributes) and returns whether LDContext.equals matches.

Harness list: removes the obsolete suppression streaming/fdv2/fallback to FDv1 handling from testharness-suppressions-fdv2.txt.
